METHOD OF CLEANING GIN'NED COTTON'.

SPECIFICATION forming part Of Letters Patent NQ. 730,158, dated J' une 2, 1903:

Application filed May 31,1901. Serial No. 62,639. (No specimens.) y

To a/ZZ whom it may concern: r Be it known that I, HENRY REMBERT, a citizen of the United States, residing at Houston, in the county of Harris and State' of Texas, have invented a new and useful Method of Cleaning Ginned Cotton, of which the following is a specification. i j This invention relates to a method of cleaning ginned cotton.

The object of the invention is in a ready, simple, thoroughlyv feasible, and practical manner to clean ginned cotton While passing from the gin to the condenser andA to eliminate therefrom all objectionable matter.

With these and other objects in view, as will appear as the nature of the invention is better understood, the same consists, generally stated, in initially subjecting the cotton to the cleaning action of a current of air, diverting the dust-laden air therefrom, and subsequently forcing a current of clean air through the cotton from a point in advance of it and in a direction at an angle to its path of movement. The invention consists, further, in initially subjecting the cotton to the action of a current of air, diverting the dust-laden air therefrom,the`n brushingthe cotton and at the same time forcing a current of clean air therethrough fromapoint in advance of it and in a direction oblique to its path of movement;

The invention consists, further, in subjecting the cotton to the cleaning action of a current of air, diverting the current of dust-laden air therefrom, forming the cotton into a sheet permeable by air, then brushing the cotton and at the same time forcing a current of air therethrough from a point in advance of it and in a direction oblique to its path of movement.

The invention consists, further, in initially subjecting the cotton to the action of a current of air, diverting the dust-laden air therefrom, and brushing the cotton and at the same time forcing a current of clean air therethrough at the point of brushing from a point in advance of it and in a direction oblique to its path of movement.

The invention consists, finally, in initially subjecting the cotton to the cleaning action of a current of air by which it is carried,diverting the current of dust-laden air therefrom, formthe purpose.

parallel with its path of travel.

ing the cotton into a sheet permeable by air, j will have aV tendency to arr themaround into effect, it being understood that themethod may be carried out in other ways than that shown and still be within the scope of, the invention, and in these drawings- Figure lA is a vertical longitudinal sectional view of one form of apparatus adapted for Fig. 2 is a similar view of a slightly-modified form of apparatus. y

The apparatus shown in Fig. l isa modiiication of a cotton-cleaner forming the subject-matter of Letters Patent of the United States, No. 530,458, granted to me December 4,1894, and which in operation is located between a cotton-gin and a condenser, neither of .which is herein indicated. ,In the patent above referred to the clean air supplied to thc apparatus is taken in' through` lateral ing proper cleansing thereof, ,while the side portions will not be properly acted upon. If the current through the fines be weak, the side portions of the sheet of cotton will 'receive the bulk of the air-currents and will thus be thoroughly cleansed, while the intermediate portion thereof will not be properly treated. In other words,the currents of air are supplied to the sheet of cotton on lines Moreover, the flues of the said patent are disposed back of the sheet and will thus operate to blow any impurities toward the fan-brush, which ICO vzo

and mix them with the incoming portion of the cotton sheet.

By the manner of supplying air to the apparatus as shown in the present invention the current is supplied` from a point in advance of the sheet of cotton and at right angles thereto and impinges its entire horizontal surface at the point where it is acted upon by the brush with equal intensity throughout. By supplying the air from a point in advance of the screen-drum any impurities in the cotton will be blown therefrom and driven into the mote-box, the result being that the sheet of cotton will be thoroughly cleansed from any extraneous matter.

Referring to the drawings, l designates a fine leading from a cotton-gin to a casing2, in which at a point opposite the inner end of the flue is located a cylindrical open-ended screen-drum 8, which is rotated by any suitable means in the direction indicated by the arrow. Dust-fines 4 communicate with the open air or with a suitable dust-collecting receptacle. Disposed within the screen-drum is a stationary shield-easing 4, which is of substantially cylindrical shape, is open at its ends, and has its side open at the point opposite and proximate to the innerend of the intake-flue l. Arranged on the side of the screen-drum opposite the intake-nue l is a revoluble brush-fan 5, which coacts with the screen-drum and also by its rotation in the direction indicated by the arrow draws air through the intake G in the casing directly above the brush-fan, and thus at a point in advance of the screen-drum, the air thus taken in being in part discharged through the outletflue 7 into the condenser, a portion of the current of air escaping in to the mote-box 4. Disposed above the screendrinn and bearing upon it is a roller S, which may be constructed of any suitable material--such as tin, wood, or the like-and revolves by contact with the screen-drum and operates to cut off passage of air from the flue l over the drum. This roller is light in weight in order that it will not operate to pack down the sheet of cotton on the drum.

The lint cotton from the gin is carried by the current of air through the flue l, and the passage of the cotton is arrested by the screendrum at the inner end of the flue, while the dust-laden air is arrested by the shield-casing l and is diverted to the iiues at the ends thereof and escapes, carrying with it the dust and other impurities dislodged from the cotton. This current of air performs the initial step of cleaning the cotton as it passes from the gin. The cotton strikes against and lodges on the screen-drum and is carried thereby upward and is subjected tothe compressing action of the roller 8, the speed of the revoluble screen being such that the cotton is condensed into a sheet of slight density which is readily permeable by a current of air. The term sheet is employed to distinguish the mass of cotton from a bat as the same is understood in this art, the sheet formed by the screen-drum and roller being of less density than a bat and of such slight texture that a current of air may be readily forced therethrough, which is not true of a bat.

The brush-fan draws in clean air through the intake 6 and at the coacting contactingl portions of the screen-drum and brush-fan, and the latter forces a current of clean air through the sheet of cotton while beating the same, the said current operating efi'ectually to discharge any foreign substance that has been dislodged by the action of the screendrum and the fan. It will be understood that the current of air created by the brush-fan operates to discharge the cleansed cotton through the flue 7, which leads to the condenser.

ln Fig. 2 of the drawings is illustrated a modified form of apparatus, in which a cardroll 9 is employed and is interposed between the screen-drinn and the brush-fan. It will be understood that this card-roll disintegrates the sheet of cotton while the same is being subjected to the action of the clean current of air forced therethrough, thereby subjecting the cotton more effectively to the action of the air-current, and, further, the card-roll serves to straighten the fibers of the cotton and to deliver them evenly to the condenser, thereby increasing the value of the product.

Having thus described the invention, what I claim isl. The method of cleaning cotton which consists in initially subjecting the cotton to the cleaning action of a current of air, diverting the dust-laden air therefrom and subsequently forcing a current of clean air through the cotton from a point in advance of it and in a direction oblique to its path of movement.

2. The method of cleaning cotton which consists in initially subjecting' the cotton to the action of a current of air, diverting the dust-laden air therefrom, then brushing the cotton and at the same time forcing a current of clean air therethrough from a point in advance of it and in a direction at an angle to its path of movement.

3. The method of cleaning cotton which consists in subjecting the cotton to the cleaning action of a current of air, diverting the current of dust-laden air therefrom, forming the cotton into a sheet permeable by air, then brushing` the 'cotton and at the saine time forcing a current of air therethrough from a point in advance of it and in a direction oblique to its path of movement.
